Unit 4: Gene Expression Review

A mutation is defined as:

• A change in the organelle structure, causing a change in protein

• Changes in cell structure, causing change in protein

• Changes in protein causing a change in DNA

• A change in the DNA sequence, causing a change in the protein

Where does transcription take place?

• nucleus
• cytoplasm
• ribosome

One difference between DNA and RNA is that....

• Only RNA has the base Uracil
• only RNA contains the base Thymine
• only RNA contains the base Cytocine
• only RNA contained the base Guanine

Which of these bases does not exist in RNA?

• C
• T
• U
• A

DNA contains the template to make RNA

• True

• False

Which RNA carries amino acids to the ribosome

• rRNA

• tRNA

• mRNA

codons are located on __________

• mRNA

• tRNA

• rRNA

• snRNA

What is rRNA?

• rRNA is a type of DNA found in the nucleus.
• rRNA is responsible for transporting amino acids to the ribosome.
• rRNA is a form of messenger RNA that carries genetic information.
• rRNA is ribosomal RNA, it makes up the ribosome

What is a missense mutation?

• a mutation that results in a premature stop codon.

• a deletion of a nucleotide in a gene.

• a mutation that results in a single amino acid change in a protein.

• a genetic mutation that does not affect protein function.
